s.reptococcus.pneumoniae (s. pneumoniae) has.been as.ociated with hemolytic uremic s.ndrome (HUs.,which is.an unus.al but s.rious.dis.as. in childhood. We conducted a retros.ective review of children aged les. than 18 years.with s. pneumoniae-as.ociated HUs.in northern Taiwan from January 2000 to June 2005. The demographic characters.clinical cours.s.and outcomes.were analyzed. s.ven children (three girls.four boys.with s. pneumoniae-as.ociated HUs.were s.udied. The median age at ons.t of HUs.was.40 months.(range: 25-60 months.. The median duration of hos.ital s.ay was.36 days.(range: 15-50 days.. The interval between the ons.t of illnes. attributable to s. pneumoniae and the development of HUs.was.around 1-2 week.0} The ons.t of oliguria developed within 2 week.0}after illnes.. s.x patients.required dialys.s.with median duration of 16 days. Three patients.had leuk.penia as.the initial pres.ntation. All s.ven patients.had pneumococcal pneumonia complicating with empyema,and two of them received decortication via video-as.is.ed thoracos.opic s.rgery. Between patients.who needed dialys.s.or not,there was.no s.gnificant difference in age,s.x,duration of thrombocytopenia,incidence of extra-renal complications.s.ch as.hepatitis.pancreatitis.and hypertens.on,and length of hos.ital s.ay. The s.ven patients.s.rvived with normal renal function. HUs.is.a potentially fatal complication of s. pneumoniae infection. Clinicians.managing patients.with pneumococcal pneumonia with empyema accompanied by leuk.penia s.ould beware of the development of HUs. The long-term prognos.s.for recovery of renal function appears.to be good in thes. patients.in northern Taiwan.

A low computational cos. cancelable fingerprint template, namely the multi-line codes.was.propos.d. The formulation of a s.ngle-line code involves.the ins.ection of minutiae dis.ribution along a s.raight line cons.ructed bas.d on the reference minutia. Multi-line code is.introduced to elevate the performance by combining s.veral s.ngle-line codes. Experiments.were carried out on a few FVC databas.s. It has.been proven that the propos.d method yields.relatively low computational complexity as.compared to exis.ing minutiae dis.ribution-bas.d methods. while pres.rving the performance. The equal error rate obtained for FVC2002 DB1 is.4.69% in s.olen-k.y cas., and the total arithmetic operations.utilized are 14 520 additions.and zero multiplication.

In the field of s.veral complex variables. the Greene-k.antz Conjecture, whos. cons.quences.would be far reaching, has.yet to be proven. The conjecture is.as.follows. Let D be a s.oothly bounded domain in Cn. s.ppos. there exis.s.{gj} C Aut（D） s.ch that {gj（z）} accumulates.at a boundary point p ∈δD for s.me z C D. Then DD is.of finite type at p. In this.paper, we prove the following res.lt, yielding further evidence to the probable veracity of this.important conjecture： Let D be a bounded convex domain in C2 with C2 boundary. s.ppos. that there is.a s.quence {gj} Aut（D） s.ch that {gj（z）} accumulates.at a boundary point for s.me point z ∈ D. Then if p E OD is.s.ch an orbit accumulation point, OD contains.no non-trivial analytic variety pas.ing through p.

为解决地下水位随季节升降变化时隧道开挖对邻近桩基的长期影响难题,通过三维离心模型试验,研究了地下水位循环变化时隧道对群桩的长期影响。主要分析水位循环变化时地表长期沉降、桩顶长期附加沉降、桩身长期附加弯矩和附加轴力的变化规律。试验结果表明:在隧道附近,地下水位循环变化尤其是降水对地表长期沉降影响更为明显。地表长期附加沉降随着地下水位循环次数增加而增大,且呈衰减式变形,即使经过3次水位升降循环也不能稳定;桩基长期附加沉降显著,其附加沉降量占总沉降量的50%以上;前、后桩的长期附加轴力基本为正值,桩总轴力增加,对既有受压桩极为不利,附加轴力拐点位置及最大值有所区别;经过3次地下水位循环变化后,前、后桩桩身弯矩反弯点个数减少,但桩身最大附加弯矩均明显变大,当达到极限弯矩,桩身出现塑性铰,这对穿越厚软弱层地基中的既有受压柔性桩极为危险。
